12. Rising inventories, when unaccompanied correspondingly by increases in sales, can lead to production cutbacks that would hamper economic growth. (A) when unaccompanied correspondingly by increases in sales, can lead (B) when not accompanied by corresponding increases in sales, possibly leads (C) when they were unaccompanied by corresponding sales increases, can lead (D) if not accompanied by correspondingly increased sales, possibly leads (E) if not accompanied by corresponding increases in sales, can lead
OG给出的答案是E,对B选项的错误解释是:Plural subject inventories does not agree with the singular verb leads. 但我认为本句的主语应该是Rising inventories,是可以用单数谓语的,请问大家对此题的看法是什么,谢谢!
